My tech replaced my previously bad Ruud RCFL coil today. It's very hot outside (92F) and when my system came back on, it ran for several hours uninterrupted. I wanted to try her out so I set my tstat to 70.
I watched over several hours as humidity in my house finally started to drop from 65%... to 61%... broke 60.... and eventually got to 55%, by which point it was actually cold in my house, so I rose the Tstat to 72.
No sooner did the AC kick off than humidity started to rise. In less than an hour, it was back to 65%.
Mind you, my house has been without proper AC for two months thanks to run-arounds with this tech. I know it's probably soaked and has a lot to pull out. But is that behavior normal? Will it really take 3-4 days before it gets to <50 consistently? I have brand new windows and a pretty well insulated and sealed house.
